| 摘 要： | 随着我国工业化进程的发展，暴露出来的土壤污染问题越来越严重。对我国2005—2019年以来455个污染场地修复项目进行了统计分析，发现我国污染场地修复项目数量逐年递增，修复方式以异位修复为主，占比为63%，修复技术以阻隔/填埋（29%）、固化/稳定化（18%）为主。相比之下，2005—2014年，美国污染场地修复方式实现了从异位修复到原位修复的转换，原位修复技术占比达到54%，其中土壤气相抽提技术、物理分离、固化/稳定化技术、化学修复和生物修复技术应用居多，地下水抽提-处理技术的应用逐年下降。基于美国修复技术发展趋势，我国未来修复技术路线应以原位修复为主。

| Abstract: | Soil pollution becomes more and more serious in China, and this paper conducted a statistical analysis of 455 soil remediation projects since 2005-2019, and preliminarily expounded some characteristics, that is, the number of soil remediation projects is increasing and the main remediation methods are off-site method, accounting for 63% of the total projects. The mainstream remediation technologies are barrier/landfill(29%) and solidification/stabilization(18%). In contrast, in-situ remediation technology(54%) was the mainstream technology for site remediation technologies in the United States from 2005 to 2014, and most of them were soil vapor extraction, physical separation, solidification/stabilization, chemical remediation and bioremediation, among which the application of groundwater extraction treatment technology decreased year by year. Based on the developing tread in the USA, the remediation technologies in China was predicted to be mainly in-situ remediation. |
